DUST ooLLnca'oR Application filed November 29, 1926. Serial K051513251.H i

heat boilers for the generation of steam.

The invention is especially useful in saving space and at the same timeutilizing theheat in an eifectlve manner, while also makmg the sameflexible so that one or more of the kilns or one or more of the boilersmay be'cut off when desired.

The invention will be understood from the description in connection withthe accompanying drawings in which Fig. 1 is .a plan view; Fig. 2 is anend view partly in'section and Fig. 3 is a vertical section along theline 33 of Fig. 1 or Fig. 2 the parts being shown somewhatdiagrammatically.

In the drawings reference character 5 indicates a plurality of cementkilns of awell known type from each one of which waste gases aredischarged into a compartment 6 in a housing. Each. compartment 6 has afloor sloping at an angle slightly greater than the angle of repose ofsoot and dust so that soot and dust will not accumulate on the floors ofthe compartments. Dampers 8 are A partments 6 all open into a lowercommon flue 10 that is horizontally disposed and is connected at one endby a passageway leading to the stack 12 with a damper 13 in thepassageway. V

Openings or passageways 14 are provided along the side of flue 10 andhave transverse Walls 14 extending along the bottom thereof. The dampers15 vertically movable in guides are provided forclosing the openingswhenever desired.

Each one of the passageways or openings 14 leads to a boiler 16 and asuction fan 17 is provided for drawing waste gases through each boilerafter which the gases pass into the passageway 18 and then into thestack 19.

PAT1.31 1515 oFFrce j HERMAN B. SMITH, 0F PLAINFIELD; New JERSEY,essrenoza TO. THE tandem a- Hoppers 20'may beprovided for collectingsoot and dust after the gases pass over the heat abstracting surfaces ofthe boilers.

The operationis asfollows :Hot gases from the kilns '5 'pass intocompartments 6 and thence downwardly into the flue 10', through thepassageways 14, over the heat abstracting surfaces of the boilers 16,into the passagewaylS and thence into stack 19. When it is desired toshut off the boilerswhile the kilns arestill being operated the dampers15 are closed and the damper 13 isopened, thus per mittingthe hot gasesto pass into the stack 12 without heating the boilers. Whenit isdesiredto cut ofl only some of the boilersnthe corresponding dampers 15are closed and the damper 13 may be partiallyopened to perm-it a portionof the hot gases from the kilns to pass into the stack 12 whiletheremainder heats the remaining boilers that are being operated. Whenone or more of the kilns 5 are not being operated the correspondingdamper or dampers Sare closed, thus permitting the gases from theremaining kilns to pass into and away from flue: 10, as heretoforedescribed. The combinations are various and all conditions need not bespecifically described.

With the compartments 6, into which the kilns 5 discharge, arrangeddirectly above the flue 10 less space is required for the installation.When the hot gases from the kilns discharge into the compartments 6-dust and soot therefrom settle in these comparatively quiescent spacesupon the floors 7 which slantv downwardly and from there'the dust andsoot pass into the flue 10 where they collect and can be removed fromtime to time. However,

if dust and soot collect upon the'floors7 they a can be removed by rakesor the like passed through the openings 9. The partitions or walls 14prevent'a large portion of the dust and soot from being carried into thepassageways '14. d i

I claim: 1 Y 1. In. combination, a plurality of kilns, separatecompartments into which gases from said kilns are discharged, a commonflue below said compartments connected to all of said compartments and adamper between each compartment and said flue.

2. In combination, a plurality of kilns, separate compartments intowhich gases from said kilns are discharged, said compartments havingsloping bottoms, and a flue to which said compartments are connected.

3. In combination, a plurality of kilns, separate compartments intowhich gases from said kilns are discharged, each of said compartmentshaving a sloping bottom and an opening along one side near the upperedge of said bottom and a common flue into which said compartmentsdischarge.

4. In combination, a plurality of kilns, separate compartments intowhich gases from said kilns are discharged, a common flue below saidcompartments connected to all of said compartments and a damper betweeneach compartment and said flue, a stack to which one end of said flue isconnected and a damper between said flue and stack.

5. In combination, a plurality of kilns, separate compartments intowhich gases from said kilns are discharged, a common flue below saidcompartments connected to all of said compartments and a damper betweeneach compartment and said flue, discharge ports along the side of saidflue and a damper in each port.

6. In combination, a plurality of kilns, separate compartments intowhich gases from said kilns are discharged, said compartments havingsloping bottoms at an angle exceeding the angle of reposeof soot anddust, and a fine to which said compartments are connected.

7. In combination, a kiln, a compartment into which said kilndischarges, said compartment having a sloping bottom and an openingthrough the wall thereof to give access to said sloping bottom.
